Study on the Airflow Level Posture Sensor Based on Fluid-Solid coupling

利用有限元仿真计算软件,采用基于流固耦合的分析方法,通过建立1:1尺寸大小气流式水平姿态传感器敏感元件的实体模型,通过仿真计算得到了气流式水平姿态传感器敏感元件内流场的分布及气流速度。基于流固耦合的仿真计算方法可以使得计算结果更加符合原件的实际工作状况。

Using ANSYS program,the finite element simulation based on Fluid-Solid coupling is conducted by a series of procedures,such as three-dimensional model building of airflow level posture sensor according to the actual size of the proportion,network modifying,loads applying and equation solving.The flow field in three-dimensional hermetic chamber of sensitive element of airflow level posture sensor is calculated.which provides more reliable basis for practical research of the airflow level posture sensor.
